What pump does Komatsu excavator use?
In the field of construction machinery, Komatsu excavators are world-renowned for their excellent performance and reliability. As one of the core components, the performance of the hydraulic pump is directly related to the working efficiency and stability of the excavator. This article will introduce in detail the types of hydraulic pumps commonly used in Komatsu excavators, technical characteristics and market feedback, and attach structured data for reference.
1. Commonly used hydraulic pump types for Komatsu excavators
Komatsu excavators mainly use the following two types of hydraulic pumps:
| Pump type | Features | Applicable models |
|---|---|---|
| Axial piston pump | High pressure, large flow, long service life | PC200, PC300 and other medium and large models |
| gear pump | Simple structure, low cost and easy maintenance | PC60, PC78 and other small models |
2. Comparison of technical parameters
The following is a detailed technical parameter comparison of the two pumps:
| parameters | Axial piston pump | gear pump |
|---|---|---|
| Working pressure (bar) | 300-350 | 150-200 |
| Flow(L/min) | 120-300 | 30-100 |
| efficiency | 90%-95% | 85%-90% |
| Lifespan (hours) | 8000-10000 | 5000-7000 |
3. Popular model matching scheme
According to the analysis of industry data in the past 10 days, the following is the matching plan for Komatsu’s mainstream models and hydraulic pumps:
| Model | Pump type | supplier | market share |
|---|---|---|---|
| PC200-8 | Kawasaki K3V112 | Kawasaki Heavy Industries | 68% |
| PC300LC-8 | Komatsu HPV95+95 | Komatsu original factory | 82% |
| PC60-7 | Danfoss G Series | Danfoss | 45% |
4. Industry hot spots and technological innovation
1.Electrification trend: Komatsu recently issued a statement stating that it will launch an all-electric excavator by 2025, and the electronically controlled hydraulic pump developed to support it has entered the testing stage.
2.Smart pump technology: Real-time monitoring of pump working status and early warning of faults are achieved through Internet of Things technology. This technology has been applied on the Komatsu PC360LC-11 model.
3.Remanufacturing market is booming: According to statistics, the price of Komatsu hydraulic pump remanufactured products is only 60%-70% of new products, but the performance can be restored to more than 90%, making it a popular choice in the recent second-hand market.
5. Maintenance suggestions
1. Replace the hydraulic oil and filter element regularly. It is recommended to replace it every 2000 working hours.
2. Monitor the temperature of the hydraulic system. If it exceeds 80℃ for a long time, it will significantly shorten the service life of the pump.
3. Choose original or certified parts. Low-quality hydraulic oil will cause abnormal wear of precision components in the pump.
6. Purchasing Guide
| purchasing factors | Suggestions |
|---|---|
| Model matching | Strictly select according to original factory specifications |
| working environment | Low-temperature start models are required in high-cold areas. |
| budget control | Remanufactured pumps are the most cost-effective |
| After-sales service | Give priority to brands with local service outlets |
Summary: Komatsu excavators mainly use two hydraulic systems, axial piston pumps and gear pumps, among which Kawasaki and Komatsu original pumps dominate the market. With the development of technology, intelligence and electrification will become the main development directions of hydraulic pumps in the future. Users should fully consider the actual working conditions and technical requirements when purchasing and maintaining to maximize the use value of the equipment.
